If you come into Keystone via Rapid City, this is looking back towards the direction you entered the town from. Looking down main street from the other side of the street, looking in the other direction. In early 2003, Keystone main street suffered a devistating fire. The fire was later ruled arson, and was found to have been started in a trash can along the raised and covered boardwalk walkway. One bright spot in all of this was the quick action of the fire fighters who battled to save main street. As you can see from the pictures above, Main street Keystone consists of several businesses that are either connected to each other, or in separate buildings that are no more than two to three feet apart. While the businesses in the area of where the fire started were totally lost, many of the businesses on that side of the road were saved and opened for business as usual that summer. The pictures below show the burned-out areas.
